“我们不做一锤子买卖，只做技术成长的长期伙伴！”

目录

一、视频展示

二、项目简介

三、原理图设计

四、PCB硬件设计

五、程序设计

六、资料分享

一、视频展示

基于STM32的智能安防监控系统设计 -视频分享

二、项目简介

题目：校园绿色照明智能控制系统
主控:STM32
BH1750传感器
oled显示
蓝牙模块
USB小灯
DS1302时钟模块
三按键

功能如下：

1、根据环境亮度，随着不同季节日照时长的不同，
     自动控制照明装置开启和关闭例如夏天时晚上7点到第二天5点为开启状态，
     冬天是下午五点到早上七点为开启状态。
2、当检测到光照不足的时候蓝牙发送手机异常提示。
3、PWM调光，根据环境光强度自动调光。
4、手机连接蓝牙，可得到单片机的数据。数据可以发送到云端

三、原理图设计

四、PCB硬件设计

五、程序设计
